To ad whom t may concern."

Be it known that we, ARTHUR FAGER- LUND, a citizen oi Finland, and EMiL-SUNILA, a citizen of the United States, both residents of the city ofNew York, borugh of Brooklyn, in the county of Kings "and State of NewYork, have invented a newand Improved Concrete-Mold, of which thefollowing is a full, clear, and exact description.

rlhis invention relates to concrete molds and has for an object theprovision oi' an improved construction of mold designed for moldingcolumns and the like in concrete buildings or separately.

Another object, in view is the provision of a mold formed from sheetmetal and arranged with means whereby thethickness of the mold may bereadily adjusted.

Another object of theinvention is to provide a mold with means foradjusting the depth and means Jfor adjusting the connection between thehead and the main part of the mold whereby the same ornamental head maybe produced on both large and small columns.

. A further object of the invention is the provision of an improvedarrangement of identical braces for holding't'he mold in a verticalposition and for adjusting the same accurately.

, A still further object of the invention is the provision oi bracingmeans or frames for holding the body of the mold in proper position.

. In the accompanying drawings Figure 1 is a rear view of the upper endoftwo molds and certain bracing means embodying the invention.

Fig. 2 is a transverse sectional view through F ig. 1 on line 2 2.

tures of the invention, the same being taken through Fig.Llapproxirnately on line Fig. 8 is a sectional view through Fig ,-A

on line 8-8.

Fig. 9 is a fragmentary perspective view of a supporting structureembodying' certain features of the invention.

Referring to the accompanying drawings by numerals, 1 indicates a -moldor form for casting concrete columns, said form being held in propershape by the bracing frame 2: The mold 1 maybe shaped in cross sectlonas shown in Fig. 3, may be shaped square or may be shaped in slightlymodilied ways without departing from the spirit of the invention, andcontinually permitting the frames 2 tol hold the front, back and sidesin proper position. As shown in Fig. 2 the back plate 3 is fiat whilethe front l'ate 4 is curved or rounded and is connected y bolts 5 to thesides 6 and 7, said' sides being iiat. All of the parts are preferablymade from sheet metal and, consequently, the frames 2 are necessary tohold the parts in proper shape while the concrete is setting. The sideplates 6 'and 7 are provided with a number of apertures foraccommodating bolts 5, as shown in Fig. 3, whereby the front plate 4 maybe in the position shown in Fig. 2 or the dotted position shown in Fig.2, as well as in other positions, so as to vary the thickness ofthecolumn from -ront to rear.

ln concrete structures, especially in concrete buildings provided withcolumns, it is customary to provide a comparatively large column on theground floor and smaller columns on the upper floors, the smallest beingon the `top floor. ln order to carry out this l ide-a and toscientifically reduce the amount of weight to be carried, the frontplate is moved toward the rear plate 3 on each loor and thereby reducesthe thickness oi the column without aieoting the width. ln

order to produce proper shaped corners at the rear, corner members 8 and9V are provided having langes 1 0 and 11 accommodating bolts which passthrough the flanges and through the back plate 3 and the side plates 6and 7 respectively. The side plates 6 and .7 are cut away at 12 and 13in order to allow a wrench to be inserted when apply` ingor removing thebolts 14 and 15.

As above mentioned, the frames 2 are provided or preventing any outwardmovement of the plates when properly adjusted. These frames are made upof bars 16,17, 18 and 19, bar 16 navlng turned over hooks 2O and 21 atthe endswhile the bars 17 and 19 have hooks 22 and 23 at one end of therespective bars and apertures 24 and 25, respectively, at the oppositeend. A pin extends through. each end of the bar 18 and through one otthe apertures 24 and 25, respectively, for holding the bar in anyposition, as for instance, that shown in Fig. 2. The hook ends ofthebars 17 and 19 overlap bar 16 whereby the various` wedges 26, 27 28and 29 may be used and caused to press the bars against the side platesandthe back plate continually and hold the same in this position duringthe casting and setting of the concrete.

' After the column has been properly set and it is desired to remove theform it would be diliicult to take the pins or bolts out of bar 18 andapertures 24 and 25 without loosening the frames 2. By constructing thewedges 26 to 29, inclusive, as shown in Fig. 2, the loosening action maybe provided by driving these wedges out, whereupon the frame may bereadily removed and aitter- 'Ward the bolts 14 and 15 removed. Ylfhiswill allow the lvarious plates oi the mold to be slipped from thecolumn. ,Y

In order to provide a proper spacing and reinforcing member for theframes an angle bar 30 is provided, which may be Sea cured directly tothe various bars 16, as

shown in Fig. 2, while a steadying bar 31 is connected by a bolt orotherwise to the upper end of bar 30, as shown in Fig. 1. The bar 31extends horizontally from one form to the other in order that the upperend oit the various forms may be properly spaced apart and held againstside movement. A suitable diagonai brace 32 (Fig. 3) is 4provided forpreventing the form from swaying toward the front or toward the back, ashereinafter fully described. ln this way the forms are properlymaintained in position for casting during the setting operation whileallowing a ready removal after the column has set. lt will be noted thatall 'the parts may be applied and removed without injury so that themolds or forms may be used over and over. j

As above stated, the columns 1n a building are of different sizes, thesmaller sizes beingarranged at the top and the larger sizes at thebottom. The heads of the columns, however, are preferably the same sizethroughout, and in order to provide a proper head a sheet metal form 33is provided, as shown Vin Fig. 5, which is held in a given shape by thebands 34 and 35 which are readily secured to the various strips of metalmaking up the head. Suitable reinforcing T bars 36 are also provided, asshown in Fig. 4, for bracing the sheets forming the head. ln order tocause the concrete casting to merge into the main column an apron 87 isprovided, formed of a plurality of plates conmedica that each plate ispivotally mounted on one of the bolts 38 and is allowed to move byreason of the slot 40 though subject to be clamped in any adjustedposition. .By providing an adjustable apron of this kind for the head 33the column will properly merge into the cast head and, consequently,will produce a complete column; The head 33 with the apron 37 isremovable andordinarily rests against the'upper edge of the plates 3, 4,6 and 7 and is held against tilting movement by suitable guy members 41and 42, said guy members being of substantially guy structure, as forinstance, a guy wire provided with a turn-buckle 43 whereby an easyadjustment is provided.

1n setting up the molds it is oftentimes more or less diiicult to havethe same perfectly vertical, and in order to provide an easy adjustmentof the parts for causing the molds to be absolutelyvertical a'diagonalbrace is provided which is connected with a rod 44, as shown in Figs. 4,7 A and 8. rllhe rod 44 is 4preferably somewhat loosely fitted into theend ot the brace 32 and pivotally mounted :f1.t45 to the top frame 2;This top frame carries at the end a .fitting 46 formed substantially Ushape as shown in Fig. 7, said fitting being of metal and provided witha slot 47 through which. the rod or bar 44 extends. rl"he rod 44 isprovided with a nut 48 which is rigidly secured thereto, and whichaccommodates the threaded rod 48', said rod extending through slots 48at each side of the frame 2 as shown in Fig. 7, so that when the rod 48is held by a wrench or other member engaging the square ends of the rodnut 4S will be moved and consequently the rod or bar 44 will be moved soas to shift the position of frame 2 and consequently the position of theupper end of the entire mold. The frame 2 shown in Fig. 7 and also inFigs. 3 and 4 is made from metal, but as disclosed in Fig. 7A and Fig. 8the lll-shaped member 46'may be secured 'to a wood 'frame 2, the partsoperating as just described. This will allow the adjusting mechanism tobe'applied to wood frames now in common use as the U-shaped fitting 4Gmay be nailed or otherwise rigidly lsecured either to a wood frame or toan extension and a proper adjustment secured in a similar manner to theway the steel or iron trame it adjusted.

lt will be noted that the forms are made from sheet metal, but it is tobe understood that other materials, as for instance, wood, may be usedwithout departing from the spirit of the invention. lt is also to beunderstood' that the diagonal bracing member 32, the rod 44 andassociated parts for adjusting the vertical position of the mold may beused with wooden molds, metallic anaemia l' y i from .I l materialrealise; departing from the Spirit of the e a', number of columns the isconnected `to the'vertical reinforcing bars s in anysuitable manner, asshown in Figs. f l and v2,f`said reinforcing bars thereby rein-Laforcing' the rear of the column and at the e" Sametime providing meansin connection with 'bar 31l for holding the forms properly a spaced.The-supporting :structure shown :in
